Experience radiant-looking skin with the 111SKIN Dark Spot Correcting Serum, developed by Dr Yannis Alexandrides. Inspired by in-clinic treatments at 111 Harley Street, the brightening serum utilises a patented NAC Y2 Complex to reduce the appearance of dark spots and minimise their future formation. n Formulated for all skin types, even the most sensitive, the serum is infused with niacinamide and glutathione to hydrate skin, visibly soothe redness, and boost radiance. Use morning and night to promote a visibly brighter, evenly-toned complexion.
